DS7832W/883

Overview

The DS7832W/883 is a single bus transceiver featuring four bits of data transmission capability. It utilizes Schottky TTL (S-TTL) logic technology and operates with a nominal supply voltage of 5 V. The device is housed in a 16-pin ceramic flatpack (DFP) package, designated as FL16,.3. It supports an extended operating temperature range from -55 °C to +125 °C. The output stage provides three-state characteristics with true polarity. This component is classified under military standards, specifically screened to MIL-STD-883B methods.

Feature Summary

• Single-ended line driver configuration for party line systems
• High drive capability with low output impedance
• Three-state outputs allowing common bus connection

Applications

• Bus-organized party line systems
• Military aerospace electronic circuits
• High-speed digital signal transmission interfaces

Procurement Notes

Verify the specific screening level required for your application, as the /883 suffix indicates compliance with MIL-STD-883. Confirm that the ceramic flatpack package is compatible with your assembly process. Ensure the S-TTL logic family matches your system voltage and interface requirements. Check for any obsolete status or lifecycle restrictions from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a single quad bus transceiver is needed for military-grade applications requiring wide temperature tolerance. The ceramic package offers superior thermal and mechanical stability compared to plastic variants. Consider the 54/74 series compatibility if integrating with standard logic families. Verify that the unidirectional control type meets the data flow direction needs of the specific circuit design.

Part Context

This device belongs to the National Semiconductor DS783x/DS883x family of line drivers and transceivers. These components are designed for high-speed data transmission in harsh environments. The DS7832 variant specifically serves as a dual differential line driver or quad single-ended driver. The /883 designation signifies military screening and reliability standards.

Replacement Considerations

The DS8832W/883 is the commercial temperature grade equivalent. The DS7831/DS8831 includes VCC clamp diodes not present in the DS7832. Verify pinout and electrical specifications against these related parts before substitution.
